BioSoap

Liquid Soap

Background
Ingredient List

Students in the Clean energy Lab turn byproducts from biodiesel production in an eco-friendly soap. Our soap is a great grease-cutting and moisturizing handsoap. BioSoap is available for purchase from the Clean Energy Lab and is also used in bathrooms across campus. We hope to have our BioSoap used as the exclusive liquid soap in bathrooms and locker rooms at Loyola University Chicago by 2015.

Background

We want to create biodiesel in a sustainable way and part of this means creating as little waste as possible. One of the by-products of biodiesel production is glycerin. After distilling excess methanol out of the glycerin, to be reused in biodiesel production, the glycerin can be used as an ingredient in soap. This allows us to be one step closer to closing the loop and creating less waste.

The liquid soap project began during Fall 2008 with a group of students enrolled in the Solutions to Environmental Problems (STEP): Biodiesel course. Prior to the liquid soap trials students previously enrolled in the STEP course had tried creating Bar Soap, but they were unable to make a consistent, quality bar soap. The students in Fall 2008 wanted to give liquid soap a shot and they eventually succeeded.

After a consistent, high quality recipe was created for small-scale batches of soap the biodiesel lab decided to scale up and start distributing liquid soap on campus. It took some time to master a process to scale up the recipe, but after several months and finding the right equipment the process was perfected and the liquid soap, BioSoap, was ready to be distributed to campus stores for sale.
